CHIMNEY.

Specification ofiLettersPatent. Patented Dec.17,1912.

Application filed February 1:, 1912. Serial No. 674,813.

To all whom it may concern:

Be it known that I, SAMUEL HEATH, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Chimneys, of which. the following is a specification.

My invention relates to new and useful improvements in chimneys adapted to be used with heating or illuminating burners, burning oil, gas or gaseous fuels.

The objects of the invention are, to provide an unbreakable chimney to take the place of the ordinary glass chimney which may be used on the ordinary house lamp,

burning either gas or oil, on automobile lamps, pilot or head lights of locomotives, mast head lights on ships, signal; lights 1n light houses, or on railroad towers, and on V thrown off from the flame to be consumed,-

allstationary lanterns.

A further object of the inventlon isfto produce a lamp chimney which will confine the heat causing the carbons and gases thereby eliminating all smoke, ."soot and odors.

Another object of the invention is to produce a chimney of metal and mica which when used with an illuminating burner IA still further object is to produce achim ney of the character described in which the casing or the metallic portion of thechimney is of one piece, either straight or conical in shape, or to form said chimney in two separable parts .so that they may be readily taken apart to clean or to renew the mica.

Further objects of the invention are .to

provide means for holding the mica,to provide means for. securing the mica to the chimney casing, to produce a flange, rib or other means to support; a lamp shade so that the light may be thrown downward.

' With these ends in view, this. invention consists in thedetails .of construction and combination of elements hereinafter set forth and then specifically designated by the claims. In order" that those skilled in the'artto which this invention appertains may under stand how to make and use the same, I will describe its construction in detail referring by numeral to the accompanying drawing forming a part of this specification, in 'which- A Figure 1, is a side elevation of a chimney made in accordance with my improvement. Fig. 2, a similar view at right angles to "Fig. 1. Fig. 3, a longitudinal sectional view thereof. Fig. 4, a' plan View thereof. Fig.

In carrying out my invention as shown in ber-2, of any suitable metal having a plurality of openings 3 thereinbeing preferably two in number and oppositely disposed, thus producing a collar 4:, a ring 5, and connecting posts 6. Thesecan be formed from a cut therefrom to form the openings 3 is so great thatljprefer to form each of these separately asshown and fastening them together by an interior metal strip 7, having rivets 8, 'or' their equivalent passing through "tlieparts. I. f Inside'of the base member is secured a hereinafter described which consists of a .lower mterlo-r rlng 9, and an upper interior below the openings 3. These rings are of smaller diameter than thebase member at the point where they are mounted and are ber atthe strips 7 leaving-room for the mica; 1 1 denotes the mica-whichlcovers the openings 3, the edges thereof being held inplace between the rings 5 and 9,the collar 4, and the ring 10. The mica sheets are cut to the desired shape and size and are then forced between the base memberand the rings 9 and 10 so that they snugly fit in place to moved for renewa the body of the chimney 12 which consists of a metallic cylindrical tube, the lower end being of sufficient size to over the upper 5, a side elevation of a slightly modified Figs. 1 to 4 inclusive, I provide a base memsuitable holding means for the micato be Fig. 8, an'edge .7

single pieceof metal, but the waste which is ring 1'0, one of which ismounted above and i spaced fromthe side walls of said base mem hold them securelybut maybe readily re- On top of the base member is mounted end of the base member. In thisbody por- .tion are formed a number of openings 13,

preferably two, in number and oppositely disposed. Over-lying these openings to cover them, are sheets of mica 14 held in place by a suitablefastening means 15 which as here shown consists of a sheet of man having a .central ..portion cut out as shown at 16 to form a framewhich is bent circularv longitudinally forming 't-Wooppositely disposed split rings 17 and 18'both being joined together by integral uprights, said uprights contactingwith each other when the holding means is in place. The rings 17 and 18 engage the mica sheets and firmly press them against the inner face of the body.

Above the-openings 13 is pressed from the body, an outwardly extending-flange 0r rib 20 which acts asa'holding means for a lamp the burner of the lamp with which it is to be used and from the, side walls-are cut the lower openingsi22 and the upper openings 23 which being coveredlby sheets of mica 24: in the same manneras described from.

my preferred formg' To; place the mica sheets in position in the, chimney, itis necessary that they be benttothe proper shape while placing them in the chimney and as v mica is very brittle, it is very difficult for the inexperienced person to place themin properly without breaking and in order to pro vide for this difficulty, I have produced a frame intovwhich themica may be readily placed and these frames placed in the chim:

ney, the frames being made for the chimney on; which they are used, exactly fit that quickly removed and the mica placed chimney and they .may be, readily and therein by any, one. This frame I have shown in Figs? to '9 inclusive-and'prefer- I ably consisting of asheet of metal body having the central portion cut out as at 25 producing}a'-relatively wide rim,- the sides and" top of which are wider than the bottom and thesesides and top are bent back upon themselves thus forming two walls 26 .and 27, but

7 thebottom having butone-portion 26- is left open to permit the insertion of'the mica be tween the walls-26 and -27 and when said mica is in position, the walls are pressed together therebyfirmly holding said mica.

I -'l;he frameis plainly shown asformed in the proper shape to fit the chimney so that it may be readily inserted.

. In practice, the chimney, is placed upon a lamp, the same as the ordinary glass chimney. The rays of light passing through the mica are broken up and certain colors subdnedthus causing those rays which pass to the outside to have the appearance of pure white and these are very bright making an excellent light for reading and in actual ftests, it has been found that a person may look directly at the light and then turn his head "asidewithout any ill eifect upon the 'eyes, being able to see just as plainly as before. Where the chimney is used upon a heating or cooking burner, it has been found that the heat is greatly intensified, and said heat is deliveredto the proper point where the best'results are .obtaine Of course I do not wish to be limited to the exact details of construction as here shown as these may be varied within the limits of theappended claims without (le parting from the spirit of my invention.

Having thus fully described my-jinvention, what I claimas new and useful is,,

1. A chimney comprising a conical base having openings therein, mica forcovering said openings, means for holding said mica in position, a body-having openings therein slidably mounted upon the I base member, mica covering saidopenings, and means for holding said-mica in position.

2. A chimney comprising a conical base having openings therein, mica for covering said openings, means for holding said mica in position, a body-having openings therein slidably; mounted upon the base member, mica covering said openings, 'means for holding said mica in position and an outwardly projecting rib pressed from the body.

3. In combination, a metallic body having openings therein, micadisposed across said openings a frame bent to fit within the body portion; and adapted to exert spring pressure upon the mica'sheets for holding "them in place against the-inner face of the body portion, a base member slidably mounted within one end of the body portion, said base having openings therein, sheets of mica disposed acrosssaid openings and means for holding said sheetsofmica in position.

chimney comprising a'conical base member having oppositely disposed openings therein, sheets of mica disposed across said openings, an upper interior ring, a lower interior ring, strips secured to said rings for spacing the latter from the walls of the base member, said rings holding the mica sheets iniplace, a metallic bodyportion' having oppositely disposed openings therein, slidably mounted upon the base' member, mica'sheets disposed Lacross'the openings in the body portion and means for holding said mica sheets in place. p a
